Construction to improve the I-5/Genesee Avenue Interchange began on
January 29, 2015 and will be completed approximately December 2018. The
City of San Diego project, which is being implemented by Caltrans, will
replace the existing six lane Genesee Avenue overpass with a ten lane
structure that will better accommodate current and future traffic
demands. Along with replacement of the overpass, the project will also
widen the freeway access ramps, add auxiliary lanes on I-5 between
Genesee Avenue and Roselle Street, and provide a dedicated path for the
exclusive use of bicyclists and pedestrians (with a terminus on the UC
San Diego campus at the intersection of Gilman Drive and Voigt Drive).
